Specification of Letters Patent. 1 Patented Jan 12, 1915,

Application filed September 12, 1913. Serial No. 789,496.

To all whom it'may concern Be it known that I, CHARLES A. Vvrirrnya citizen of the United States, residing at Jewell, inthe county of Jewell and State of Kansas, have invented new and useful Improvements in Boring-Machines, of which the following is a specification.

This invention relates to improvements in boring machines and has particular application to a post hole auger.

In carrying out the present invention, it is my purpose to provide a machine of the class described whereby post holes and the like may be bored out and the dirt removed from the excavation succeeding the boring operation.

It is also my purpose to provide a post hole auger which will embody in its construction a frame supporting a trackway above the ground, and a car adapted to travel upon'such trackway and carrying a derrick, the latter supporting an anger or boring tool so that such tool may be actuated for boring purposes and subsequently moved with theicar so that the material may be removed from the vicinity of the excavation and dumped. v

' Furthermore, I aim to provide a post hole boring machine which will embrace the de sired features of simplicity, efliciency" and durability and which may be installed and maintained at a minimum expense and transported from placeto place with ease and facility.

lVith the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claims. I

In the accompanying drawings; Figure 1 is a view in side elevation of a boring machine constructed in accordance with the present invention, the same being shown as in use. .Fig. 2 is an end View of the machine. Fig. 3 is a horizontal sectional view throughthe same, parts being shown in top plan. Fig. 4L is a vertical sectional view through the machine;

Referring now to the accompanying'drawings in detail, A designates a supporting frame comprising, in the present instance, longitudinal base bars or skids 1, 1 spaced apart in parellelism and connected to each other through the medium of cross bars 2 and a number of vertical uprights 3 secured to the top side of each bar or skid 1 and extending upwardly therefrom and appropriately-spaced apart. Suitably fastened'to the upper extremities of the uprights 3 are longitudinally extending bars 1 arranged in parallel relation and each provided on its upper surface with a' track rail 5, such rails cooperating to form a trackway. I

Mounted upon the trackway formed by the lines of rails 5, 5 and adapted to trav erse the same is a'car- 6 composed,in this embodiment of my invention, of longitudinal side bars 7, 7 preferably connected to each other through the medium of end bars 8, 8 andprovided with depending bearings 9 having journaled therein peripherally grooved rollers 10 resting upon the rails of the trackway and designed to ride thereon,

a base/plate 11 spanning the side bars 7 7 and forming, in effect, what is known as a flat car. Suitably fastened to the opposite side bars 7, 7 of the car preferably adjacent to one end of the latter anduprising therefrom in parallelism are standards 12, 12 i connected at their upper extremities through. the medium of a cross bar 13 and forming a. derrick, the standards 12, 12 being preferably reinforced through the medium of diagonal braces 14 eachhaving one end fastened to one of the side bars of the car and the opposite extremities secured to the respective standards approximately centrally of the latter. I I

Suitably fastened to one end pair of uprights 3 is a hoist 15 composed of boxings 16, 16-each fastened to one of the respective uprights and provided with alining bearings in which are journaled shafts 17, 17 one of which is equipped with a drum 18, while the other is provided with a crank handle 19, the shafts being geared one to the other through the medium of gear wheels 20 meshing with each other so that when the crank handle 19 is revolved, motion will be transmitted from one shaft to the other. Fasten'ed to the drum 18 and wrapped there about is a cable 21 or the like having the upper end thereof passed over a pulley wheel or sheave 22 journaled within a block 23 swiveled to the under side of the cross bar 13 spanning the upper ends of the standards 12, 12, while passed through an aperture in the base plate 11- of the car is an elongated squared or non-circular stem 24 adapted for rotary movement and having the upper end thereof connected to the free extremity of the cable 21. Mounted upon the stem 24 and slidably receiving the same and surmounting the base plate of the car is a bevel gear wheel 25 with which meshes a bevel pinion 26 keyed upon one end of a shaft 27 journaled in a bearing 28 carried by one of the standards 12 of the derrick, such shaft 27 being provided with a handle 29 whereby rotary motion may be imparted to the bevel gear wheel 25 and the stem 24. The opposite standard 12 of the derrick is provided with a bevel pinion 30 meshing with the wheel 25 and cooperating with the driving pinion 26 to maintain the bevel gear wheel in a true horizontal plane andhold the same against displacement. Suitably fastened to the lower end of the stem 24 and depending therefrom is an anger or boring tool 31 of some suitable construction.

In the present instance, the end uprights 3 carrying the hoist are extended upwardly beyond the bars 4, while the adjacent end of the car is formed with outwardly projecting lugs 32 formed with apertures alining with openings in the upwardly projecting ends of the respective standards to receive pins 33 so that the car may be anchored at one end of the trackway, the opposite end'of the car being provided with hooks 34 adapted to engage eyes 35 carried by the bars 4, 4 and cooperating with the lugs 32 and pins 33 to hold the car against movement. Spanning the rails of the trackway at the end of the latter opposite from the upwardly projecting ends of the respective pair of standards 3 is a bar 36 forming a stop so that when the car is released and moved along the trackway the travel thereof will be limited. Interposed between the top surface of the base plate of the car and the bevel gear wheel 25 is an anti-friction bearing 37 upon which the gear wheel rotates.

From the foregoing description taken in connection with the accompanying drawings, the construction, modeof operation and manner of employing my invention will be readily apparent; normally the car 6 is anchored at one end of the trackway as illustrated in Fig. 1 of the drawings and a pin 38 is passed through the stem 24 and rests uponthe upper face of the hub of the bevel gear wheel 25 so as to support the stem and boring tool without placing the weight of such stem and tool on the cable. When it is desired to use the machine, the pin'38 is withdrawn and the hoist actuated to lower the stem and boring tool carried thereby. As the boring tool contacts with the adjacent portion of the ground, the cable 21 becomes slack and the handle 29 on the shaft 27 is rotated thereby-rotating the stem 24 and imparting a similar movement to the tool with the effect to bore out the hole. After the auger has entered the earth for the desired distance, the hoist is put into operation to take up the slack in the cable and withdraw the auger from the excavation. The car is now released and slides toward the opposite end of the trackway carrying with it the auger which is relieved of the dirt or other material thereon.

I claim:

1. A device of the class described comprising a frame, a trackway on said frame and elevated above the ground, a car on said trackway, means for anchoring said car at one end of the trackway, a boring tool carried by said car, meansfor rotating said boring tool, and means for elevating and lowering the same.

2. A device of the class described comprising a frame, a trackway on said frame and elevated above the ground, a car on said trackway and adapted for movement therealong, means for anchoring said car on the trackway, a stem passed through the car and adapted for sliding movement, a hoist for elevating and lowering said stem, means for rotating said stem, and an auger carried by said stem.

3. A boring machine of the class described comprising a supporting frame, a trackway on said frame and elevated above the ground, a car on said trackway and adapted to traverse the same, means for limiting the movement of the car on the trackway, means for holding said car stationary on the trackway, a hoist carried by said frame, a stem passed through said car and adapted for sliding movement, a derrick on the car supporting said stem, connections between said stem and hoist whereby the stem may be elevated and lowered, an auger carried by said stem, and means for rotating said stem to impart movement to said auger.

In testimony whereof I aflix my signature in presence of two Witnesses.
